EARL L. MARTIN, OF MIAlv'II, FLORIDA,

CASEMENT-VINDOW HOLDER.

Application filed July 18,

To all whom it m ag/ concern.'

le it known that I, EARL LEONARD Male TIN, a citizen of the United States, residing at Miami, county of Dade, State of Florida, have invented a certain new and useful lmprovement in Casement-lVindow Holders, of which the following is a full, clear, and exact description.

My invention relates to easement window holders and has for its object to providey a new and improved folding Casement window adjuster. It further has for its object to provide a easement window holder which in folding telescopes so as not to hang down or project full length into the room. It fur ther has for its object to provide a holder of that type, which will lock the window closed or lock it in a plurality of non-closed positions through a screen.

The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which Figure 1 shows plan views of two casement holders adapted, respectively, to open and close easement windows;

Fig. 2 shows a vertical longitudinal section of one of these holders on the line 2 2,

Fig. 1;

Fig. 3 shows a section on the hne 3 3, Fig. 1;

Fig. 4 shows an enlarged detail of the end of one of the telescoping members;

Fig. 5 shows a section of the same on the line 5 5, Fig. 4; and

Fig. 6 shows an enlarged horizontal longitudinal section ofthe holder extended.

Referring more particularly to the drawings 2 2 are easement windows hinged to the sash at- 4-4. This sash has a screen strip 6 for supporting a screen 7 and having openings through which the easement holders extend. Each opening is provided with a slide plate 8 which is backed by felt 10 so as to make close engagement with the casement holder preventing the entrance of mosquitoes and the like. The sliding plate 8 is carried by a housing 12 mounted on the rail. T his housing carries a vertical anchorage pin 14 with which the rtd of the holder makes engagement so as to hold the window closed or noniclosed. The rod of the holder is a telescoping rod consisting of three sections 16, 18 and 2O adapted to slide one within the other, so that the parts may telescope as shown in Fig. 2, or may be extended as 1924. Serial N'o. 726,661.

in Fig. 6. The member 16 is pivoted to the ears of a plate 22 and a spring 24, oneend of which bears against said plate andthe other end of which enters within the mem-` ber 16, a-nd tends to move the rod toward the vertical pin 14. I Vithin the hollow telescoping rod there are two locking detents 26 and 28 which move outward and inward through aligning openings in the ends ofthe telescoping members. The inner ends of these detents yhave projections which are guided by plates 29, springs 30 being provided which tend to move the detents out-v ward. These detents are lprovided with lon- 32 will unlock its detentv slightly before the wedge 34 will unlock its detent. The-spring 36 retracts the wedges 32 and 34 when the handle 38 is released so as to withdraw them from the detents 26' and V28 and permit those detents to move out so as to ei'igage the openings in the outer telescoping members as shown in Figs. 5 and 6 when the rod is fully extended. The inner member 16 is also provided with a locking hook 42 carried by a spring arm and normally engaging the outer Surface of theV portion 16.V lVhen the rod is collapsed the member 18 is forced behind the hook 42 whose head is so shaped that the hook 42 does not interfere with the collapsing of the rod. The rod is provided with a handle 44 surrounding the operating member 38 which caneasily be grasped for opening and closing thev casen'ient window.

lVhen the window is closed and the rod is collapsed as shown at the right hand portion of Fig. v1, the hook 42 engages the pin 14, locking the window in that position, the spring d4 moving the rod so as to hold the hook in position. Then it is desired to open the window, the handle 44 is first pulled so as to extend the rod. Then it is fully extended the detents 26 and 28 are forced outward so as to lock the parts in such a way as to hold the rod in extended position. The rod is then moved sidewise to disengage the hook 42'and then pushed, and

when the window is partially opened a notch 46 formed partially in the detent 28 and partially in the rod is made to engage the pin 14 so as to hold the window rfixed, the spring 24 acting to move t-he rod toward the pin 14 and keep it in engagement therewith. When it is desired to partially open the window at another angle, the notch 48 is brought into engagement with the pin 14. When the window is fully opened the notch V47 is made to engage the vertical pin 14 as Ather 'pulledVV so as to cause the wedge 34 to retract its detent 28 and the handle is again pushed so as to cause the member 2()V to slide upon the member 18, thus bringing the rod into the position shown at theright oftF ig. 1, Vthe hook 42y acting to hold the member 16 during the pushing operations referred to.

In order to prevent relative axial movement of the teleseopmg members the inner Vmembers 16 andv 18 have slots 49 in which travel the ends of screws 50 carried bythe members 18 and 20. 1

VvThe operating member is provided with ahead 52 which acts as a stop when the member is vfully retracted.

The wedges are provided with rheads 54 to which the chains 40 areY connected, these heads being riveted or otherwise secured to the wedges.

, With this construction a very neat, eollapsible easement window holder is obtained which not only does not protrude out in the room but does not hang down and which can be operated Without danger to the user. It further permits the windowto be screwed without interference with the adjuster.

As will be evident to those skilled in the art, my invention permits of various modifications without departing from the spirit thereof or the scope of the appended claims.

Y Vhat I claim is:

1. A easement window holder comprising a plurality of tubular teleseoping sections, means within said tubular sections normally tending to lock said sections when in extended position, and means partiall within said tubular sections movable longitudinally et' said holder for withdrawing said locking means when desired so as tov permit said seea tions to telescope.

2. A easement window holder comprising a plurality of telescoping sections, means normally tending to lock said sections when in extended position, and means movable e longitudinally of said holder for withdrawing said locking means when desired so as to permit said sections Y to telescope, the easement for said window having an anchorage and said rod having a notch adapted to engage therewith, and a spring normally tending to move said rod toward said anchorage. i

3. A easement window holder comprising a plurality oftelescoping sections, means normally tending to lock said sections when in extended position, and meansfmovable longitudinally of said holder for withdrawing said locking means when desired so as to permit said sections to telescope, the easement for said window having an anchorage and said rodhaving a notch adapted to engage therewith, and a sprin normally tending to movesaid rod towar said anchorage, the inner member of said rod having a yielding detent adapted to engage said anchor'- age when said lwindow is invclosed position.

4. A easement Window holder comprising a plurality of teleseoping sections, means normally tending to lock said sections when in extended position, and means extending through `said rod rfor withdrawing, and a spring within said rod adapted to retract Y said withdrawing means.

5. In a wmdow casementholder the combination ofv a plurahty of telescopmg members, a plurality of detents for holding the sections thereofl in extended position, means for normally holding said detents in holding position when said holder is extended, means for withdrawing said de-tents from holding position, an operating member, flexible connections within said rod connecting said means and said operating member together, and a spring for retracting said withdrawing means when said rod is extended, the means toward the inner end of the rod acting to withdraw its detent prior vto the means nearerzthe outer end of the rod.
